Question

(PYTHON) Write a program that displays the following menu:. , Write Algorithm for Code

Geometry Calculator

1. Calculate the Area of a Circle

2. Calculate the Area of a Rectangle

3. Calculate the Area of a Triangle

4. Quit

Enter your choice (1 - 4):

• If the user enters 1, the program should ask for the radius of the circle and then display its area.
• If the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle's area.
• If the user enters 3, the program should ask for the length of the triangle's base and its height, and then display its area.
• If the user enters 4, the program should end.
• The user should be able to complete as many calculations as he/she wishes until a choice is made to quit.

Input Validation:

• Do not accept values outside the range of 1 and 4 when selecting from the menu.
• Do not accept negative values for any input amounts (ie. radius, length, width, etc).

Answer 1

while True:

prompt = '''\n

1. Calculate the Area of a Circle

2. Calculate the Area of a Rectangle

3. Calculate the Area of a Triangle

4. Quit

Enter: '''

choice = int(input(prompt))

if choice == 1:
